A misfiring engine will cause, low gas mileage, low power output, increased emissions and possible internal engine damage if left untreated. Typically an engine misfire under load, will be a problem with the ignition system, while low engine speed problems will be a vacuum, fuel management or compression issue.
Coral colonies grow through a form of asexual reproduction known as budding, in which polyps divide themselves to form new polyps . Corals can also reproduce sexually by spawning, which in Platygyra daedalea involves the release of gametes into the water, for external fertilisation. Platygyra daedalea is hermaphroditic, meaning that each polyp produces both eggs and sperm.
The oviparous form of reproduction, egg-laying, is considered a primitive form and common for benthic, littoral, and bathyal sharks, about 40% of shark species. Tough egg cases are laid on the substrate or attached to structures on the sea floor.
